Hi everyone! System: Processores: (4x) Intel(R) Xeon(R) CPU E5430 @ 2.66GHz Lighttpd: 1.4.19 PHP: 5.2.0-8+etch10 (cgi-fcgi) With APC: 3.0.18 First case: "max-procs" => 1 AND irqbalance on "PHP_FCGI_CHILDREN" => "52" Time per request: 1122.583 [ms] (mean) Time per request: 1148.055 [ms] (mean) Time per request: 1143.948 [ms] (mean) "max-procs" => 4 irqbalance off "PHP_FCGI_CHILDREN" => "13", Time per request: 1207.086 [ms] (mean) Time per request: 1192.972 [ms] (mean) Time per request: 1202.770 [ms] (mean) In all case the processor goes to top. This show it is better to put max-procs equals to one and start the irqbalance then use one max-procs per processor with irqbalance off. And it's good to APC memory cache! :) Obs.: note that you need a kernel compiled with SMP option.

Now it's not clear what the cause of the differences is. Is it procs/children or irqbalance? BTW, 1150 ms per requests seems extremely high.
